Installation Preparation
Warning
Statement 1017 Restricted Area
This unit is intended for installation in restricted access areas. A restricted access area can be accessed by
skilled, instructed, or qualified personnel.
Warning Statement 1021 SELV Circuit
To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network voltage
(TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some LAN and
WAN ports both use RJ-45 connectors. Use caution when connecting cables.
Warning
Statement 1024 Ground Conductor
This equipment must be grounded. To reduce the risk of electric shock, never defeat the ground conductor or
operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical
inspection authority or an electrician if you are uncertain that suitable grounding is available.
Warning
Statement 1028 More Than One Power Supply
This unit might have more than one power supply connection. To reduce risk of electric shock, all connections
must be removed to de-energize the unit.
Warning Statement 1029 Blank Faceplates and Cover Panels
Blank faceplates and cover panels serve three important functions: they reduce the risk of electric shock and
fire; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the
flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers,
and rear covers are in place.
Warning
Statement 1030 Equipment Installation
Only trained and qualified personnel should be allowed to install, replace, or service this equipment.
